What gel system are you using now? I used Brisa for several years, and found that in general, it was too flexible for most of my clients. It worked pretty well on those with thicker, stronger natural nails, but not well at all on the thinner nail plates. I currently use YN Synergy gel, and find it works on more of my clients because it's a bit more rigid. Still flexible like a hard gel should be, and easy to file, but tougher and not as bendy.
